NRL-PL 170

NRL-PL 170 was a series of three small calibration satellites built by the Naval Research Lab (NRL). These satellites consisted of one gold plated sphere (#A) and two polished aluminum spheres (#B, #C), each with a mass of 0.7 kg and a diameter of 26 cm.

The three spheres were launched on 17. February 1971 as piggy-back payloads together with the DSAP-5A F3 meteorological satellite by a Thor-DSV2U Burner-2 from Vandenberg AFB.
